Abstract (en)
According to one embodiment, an image reading apparatus includes an illumination unit (22) to irradiate a sheet (1) that is conveyed by a conveyance unit (12) with visible light and infrared light, an imaging unit (23) to receive visible light and infrared light reflected from the sheet and to capture a visible image and an infrared image, and a background member (27) including an infrared light low reflective part (29) that is positioned within an imaging range of the imaging unit (23) so as to overlap at least a side edge portion of the sheet and that diffusely reflects visible light and reflects infrared light at a lower reflectance than the sheet.
